Seeking change. Looking at FinTech etc

Hi. I'm a 9yr exp full stack engineer. Have done webdev mostly. Currently earning around 30lpa I want a job change because: 1. More money 2. Bored of webdev I was looking around and HFT seemed interesting to me. I haven't done my full research on it, but from what little I have done, it seems like it is a very niche vertical requiring highly skilled folks and also we don't have HFT companies in India? Anyways, I'm not fixated on HFT, that's just one avenue I explored. I just want some better paying programming job where I can feel livelier. For eg., when I do complex DB queries for debugging and reports, or digging and parsing logs to find patterns and debugging, or optimizing some piece of code to squeeze more performance out of it. I am fine with writing basic routine to make bucks but it's not fulfilling. Please advise how to go about my career progression in a fulfilling way.
